Power tool

A power tool system comprising:

• a tool device defining a cutout extending through the entire material thickness of the tool device;
• and
• a power tool comprising:
• a tool receiving device configured to be moved in rotation about an output axis and hold the tool device on the power tool such that the output axis and a tool rotation axis substantially coincide, the tool receiving device comprising:
• at least one driving device having at least one torque transmission region arranged at a distance from the output axis and configured to transmit a driving force to the tool device;
• and
• a clamping device that is movable relative to the driving device between a first position, in which the tool device is released from the clamping device, and a second position, in which the clamping device clamps the tool device to the power tool,
• wherein:
• the driving device and the clamping device are configured to extend through the cutout of the tool device,
• the output axis extends through the cutout,
• the tool device is configured to be received in the tool receiving device, the tool receiving device holding the tool device on the power tool such that the output axis of the power tool and the tool rotation axis substantially coincide,
• the clamping device has at least one clamping surface configured to transmit an axial action of force to the tool device,
• the tool device has a connection device defining the cutout, which is configured to at least partly encompass the tool receiving device of the power tool in a circumferential direction,
• the tool device has at least one torque take-up region that is spaced apart radially from the tool rotation axis, the torque take-up region at least partially delimiting the cutout in a radial direction,
• the driving device and the clamping device are configured to reach through the cutout of the tool device, and to clamp the tool device to the tool receiving device by rotation of the clamping device,
• the tool receiving device has a flat seating surface that is configured to support at least one contact surface of the tool device in the axial direction such that the seating surface extends, in the radial direction of the tool rotation axis, between a radial inner distance and a radial outer distance from the output axis,
• the connection device of the tool device has at least one clamping wing, which at least partly delimits the cutout in the radial direction and which is delimited substantially in the radial direction in relation to the tool rotation axis by a first delimiting edge that lies on a first delimiting circle around the tool rotation axis, and
• when the tool device is fastened to the power tool, the first delimiting edge of the clamping wing of the tool device projects radially inwardly from the radial inner distance of the seating surface such that in a region of the first delimiting edge there is no support material present for supporting the clamping wing.

A power tool, comprising:

• a tool receiving device configured to be moved in rotation about an output axis and hold a tool device on the power tool such that the output axis and a tool rotation axis substantially coincide, the tool receiving device comprising:
• at least one driving device having a plurality of torque transmission regions arranged at a distance from the output axis and configured to transmit a driving force to the tool device;
• and
• a clamping device that is movable relative to the driving device between a first position, in which the tool device is released from the clamping device, and a second position, in which the clamping device clamps the tool device to the power tool,
• wherein:
• the at least one driving device and the clamping device are configured to jointly extend through a cutout of the tool device through which the output axis extends and are adjacent to one another in the cutout, the cutout extending through the entire material thickness of the tool device, and
• the driving device delimits an opening, and the clamping device is movable within the opening and is guided by the driving device within the opening.
